Describe the content of the image

If you were describing the image to someone who couldn’t see it, what would you say?

<img src="/farm.jpg" 
     alt="Rustic barn surrounded by rolling hills">

Linked SVG that conveys meaning

<img src="/smartphone.svg" 

Images that are decorative

When the alt attribute is empty, the screen reader ignores it. The alt attribute is still required to be valid html.

<img src="/smartphone.png" alt="">

<img src="/smartphone.png" alt>

Inline SVG that conveys meaning

<svg role="img" focusable="false">
  <title>Accessible Name</title>
  <use xlink:href="#svg-id" aria-hidden="true" />
  <!-- if not using <use> then the child elements 
       of the inline SVG would go here -->

Inline SVG <use> that conveys meaning

<svg role="img" aria-label="Name" focusable="false">
  <use xlink:href="#..." aria-hidden="true"></use>

Inline SVG that is decorative

<svg aria-hidden="true" focusable="false">
  <!-- ... -->

Animations (like gifs) can be accessible if:

  • they are set to stop after 5 seconds or
  • if users are presented with a way to pause it
